    摘要： The invention relates to a fluid system with a safety-related valve assembly (3) which has a first fluid connection (29) for fluidically connecting to a fluid connection of a fluid source (13) or of a control valve (2; 62), a second fluid connection (30) for coupling a fluid load (59), and a fluid channel (35, 36, 37, 38) between the fluid connections (29, 30), wherein a first valve means (33) which can be actuated between a fluid supply position, or open position, and a fluid discharge position, or closed position, is arranged in the fluid channel. A second valve means (48) which can be adjusted between an open position for the fluid channel and a throttle position for the fluid channel is arranged in the fluid channel (35, 36, 37, 39), and a sensor means (45) for detecting a fluid pressure and for outputting a fluid pressure-dependent sensor signal is arranged in a section (36) of the fluid channel (35, 36, 37, 38) between the first valve means (33) and the second valve means (48). The fluid system also comprises a controller (47) for processing the sensor signal and for processing control signals for the valve means (33, 48).

    摘要： The invention relates to a valve arrangement for the supply of a fluid to a fluid consumer, having multiple main valves (7, 8, 9, 10) which are designed for influencing fluid flows at fluid ports (15, 34), and having electrically actuable pilot-control valves (5, 6) which are designed for fluidically actuating the main valves (7, 8, 9, 10). It is provided according to the invention that the main body (14) is assigned an oppositely situated port plate (20) through which there extends a fluid duct (44) which opens into a working port (4) for the attachment of a fluid consumer, wherein, between the port surface (12) and the port plate (20), there is arranged a separately formed duct body (16; 66) which has at least one port duct (36) for a fluidically communicating connection between at least one of the fluid ports (15, 34) and the working port (4) and at least one connecting duct (37) for fluidic coupling of at least two fluid ports (15, 34).

    摘要： A pressurized air muffler (3) is proposed that is penetrated by an unobstructed air flow channel (7). A section of the length of the air flow channel (7) penetrates a sound-absorbing device (14) and joins on said sound-absorbing device with an air escape opening (17) to an expansion chamber (37), which is delimited by a multi-layer closing wall (35). The closing wall is penetrated by an air outlet channel (38) disposed in a laterally offset fashion relative to the air escape opening (17) and free of overlap, said closing wall comprising a sound-absorbing layer (46) that faces the expansion chamber (37) and is flanked on the rear thereof by a sound reflection layer (47).

    摘要： The invention relates to a control valve device (1), comprising two main valves (HV1, HV2), each of which can be actuated by a pilot valve (VV1, VV2) so that they can be switched into a working position in which they cause a pneumatic pressure to be present at two main outlets (17, 18). The structural design of the safety valve device (1) causes a switching of the main valves (HV1, HV2) into a working position only if the two pilot valves (VV1, VV2) are actuated substantially synchronously. If, as a result of asynchronous actuation, only one of the main valves is switched into the working position, this error status remains stored until a reset takes place by way of a restoring valve device (RV).
